Contaminated drinking water is becoming a pressing issue in cities post-wildfires, particularly in Los Angeles, where utilities have issued "Do Not Drink" advisories due to the infiltration of toxic chemicals from fires. Pasadena Water and Power issued a rare advisory after testing indicated potential contamination, which was later mostly lifted. Experts highlight that wildfires can damage infrastructure, allowing ash, smoke, and soot to enter water systems, especially when system pressure is compromised by high water demand or power outages. The health risks from such contamination can vary, including temporary symptoms and long-term consequences like cancer.
